I'm unable to reproduce internally :( I'm wondering if the external docker image is somehow different. I will try to reproduce starting from the OSS version.

Could you update which model name you've used? (probably not lm.ptb.PTBCharTransformerSmallSgd)

Thanks for looking into this, Laurent! It's actually lm.ptb.PTBCharTransformerSmallSgd:

% bazel run -c opt     lingvo/jax:main --  \
   --model=lm.ptb.PTBCharTransformerSmallSgd  \
   --job_log_dir=/tmp/jax_log_dir/exp01 --alsologtostderr

I noticed that lingvo/jax/pip_package/build.Dockerfile does not specify dependency versions explicitly, so maybe we are using different versions of TF?

I see:

tensorflow                        2.8.0
tensorflow-datasets               4.5.2
tensorflow-hub                    0.12.0
tensorflow-io-gcs-filesystem      0.24.0
tensorflow-metadata               1.7.0
tensorflow-text                   2.8.1

My TF versions for python3.7 are exactly the same as yours.

Otherwise, it's definitely not the main issue. But just for the records, we didn't open source configs on PTB like lm.ptb.PTBCharTransformerSmallSgd, so you may want to try out with e.g. lm.lm_cloud.LmCloudSpmdTest instead.
